Access SharePoint web service in soap ui

Hi,

we are trying to access the SharePoint Web services (lists.asmx, Search.asmx) through Soap Ui tool. we are sending the request but not able to receive the correct response. is there any documentation available for SharePoint web services?

we are sending the below request to get the result for the search key word.

can anyone help me on this issue?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:Microsoft.Search">
<soapenv:Header/>
<soapenv:Body>
<urn:Query>
<!--Optional:-->
<urn:queryXml>

<QueryPacket xmlns="urn:Microsoft.Search.Query" Revision="1000">
<Query domain="QDomain">
<SupportedFormats>
<Format>
urn:Microsoft.Search.Response.Document.Document
</Format>
</SupportedFormats>
<Context>
<QueryText language="en-US" type="STRING">Cloud</QueryText>
</Context>
</Query>
</QueryPacket>


</urn:queryXml>
</urn:Query>
</soapenv:Body>
</soapenv:Envelope>
